26. Test Settings: Expert Mode - Manual
Use buttons to specify the parameters for testing
Range: set to 1.5 to 2 x length of fiber under test including launch/receive cables
Pulse: (see next slides)
Narrow pulses are best for resolving close events but are limited to short links.
Wide pulses are good for measuring long links
Time (Averages): (see next slides)
Traces are always averaged over hundreds or thousands of pulses.
The trade-off is time vs. trace quality.
After about 3 min, you get very little additional improvement
Filter: selectable as On or Off,
Smoothes choppy traces.
As a rule of thumb use with PW 1us or greater

27. Range Too short: less than link length
Good: about 1.5x to 2x link length
Too long: much larger than link length

If moving files it is recommended to copy and paste them not cut them
Assure you have made a successful copy before cutting or deleting files/folders
Example: 1310nm tests selected for copying
Up/down & select were used to select the tests

51. Using an OTDR
You must use a launch cable to measure the loss of the near-end connection
You must use a receive cable to measure the loss of the far-end connection
Both cables must use the same type fiber (50 m, 62.5 m, or single-mode) as the link under test
For testing links under 2 km, the length of the launch and receive cables should be about 100 m, for long fibers under test, longer launch and receive cables may be needed

52. No launch or receive cable
Link
Without launch and receive cables the OTDR cannot measure the IL of the near-end or far-end connections.
This is a problem in premises links, which are typically short, because these connections represent a large portion of total link loss.

53. Launch Cable

Adding the launch cable enables the OTDR to include the loss of the near-end connection in total link loss calculations, and measure its reflectance A B

54. Adding the receive cable
